Charging starts on time, turns off, then charges exactly 3 hours late

[RickMachE]

Yesterday the car needed to charge. At 7PM, on schedule, it became to charge, but stopped 5 seconds later. Then at 10PM it started to charge, and completed charging 45 minutes later.

Looking at my JuiceBox data, it also did this on 7/22. It charged correctly at 7PM on 7/25, 7/21.

The JuiceBox is set for the same 7PM start, and it shows the time correctly.

The car is correctly set for 7PM start.

Any ideas?

Your car likely starts at a point where the Juicebox is not on, and then it has some built in delay to try again. I do not use any scheduling in my EVSEs, do it all in the car, in order to avoid these issues. If you have a reason for doing it in both, I suggest you set the EVSE to turn on 30-60 minutes before the car tries to charge, and for some extra time after you expect it to finish.

I set my cars to charge only during off peak, but at least with my Bolt, it will occasionally condition the battery during on-peak, but at a very low kw level. I would like for the Mach E to do that also, but it does not, even when the garage is 100+deg.

Yep, AZBill nailed it. You need to only use 1 schedule to avoid mis-haps with lag time. Or use buffer periods on the EVSE. Better yet, disable all schedules and just plug in when needed. Then you are in control and not some buggy Ford code. I swear everyday someone complains about how crappy the Mach-E charge schedule code is and how it didn't work in some new way. I get that starting at like 2 or 3am might be hard. But 7pm? Do it manually.

If you are going to trust a scheduler, I'd go with only the Juicebox. Not the Mach-E.

JuiceBox is on, and records the session just fine. Car is initiating session, then car is turning it off.

Maybe when the MME does it's checks, the JuiceBox isn't yet ready to roll? Why not just use one schedule like suggested? Or maybe do the JuiceBox schedule 5 minutes earlier and I bet that solves it.

Does this have to do with your utility control? Maybe they are delaying charging.

It has been this way for a year with no issues, and it shows in the JB app that the car is charging for the few seconds it does. If you prevent charging on the JB app, the car will tell you that charging failed to start.

I don't think they are, but I did notice that while the times were right, it's possible there's some weird plan attached, I'll be pursuing that.

Hello,

had some issue with charging also. I have ChargePoint home flex. Used the car to set the charge timer 12AM to 9AM every day and haven’t change it. Plugged in at 6:30PM when I got home expecting a full charge when I wake up next morning only to find out it started charging at 4AM not 12AM as set.
Anyone else have this issue? Will see if this happen again tomorrow.

Is your ChargePoint a smart charger? Do you have a schedule set on that?
